This invention relates to a safety pin.

Safety pins frequently come unclasped due to pressure being lexertedupon the member which has the pointed endand .this is a'source ofannoyance when the same is inuse, particularly whenused uponchildren orbabies, where there is a danger of. the baby in bed rolling upon a pinafter il; has become unclasped, with fthe lifesult that the point'ofthepinwillfstick into the child. This fault is particularly noticedwhere diapers are used on .babiesl and safety pins are used for securingthe same.

One 'of the objects of this invention is to provide a safety pin' whichcannot become un- 4clasped due' to usual' pressure' upon the pointedmember of the pin which is ordinarily used for detaching this pointedmember from its clasp.

Another object of this invention is to provide a safety pin which may beoi such construction that it may be readily manufactured by machineoperations.

Another object of this invention is to provide a safety pin which,although the same will not accidentally become unclasped, may be readilyunclasped by the use of two hands for detaching the pin stem from itsclasp.

Another object of this invention is the provision of a safety pin whichmay be clasped by one hand.

With these and other objects in view, the invention consists of certainnovel features of construction, as will be more fully described andparticularly pointed out in the appended claims.

In the accompanying drawings:

Fig. 1 is a perspective view of the pin in clasped position;

Fig. 2 is a section on line 2 2 of Fig. 1;

Fig. 3 is an elevation showing the wire portion of the safety pin priorto the assembly of the guard thereon;

Figs. 4, 5, 6, '7 and 8 are sectional Views through the guard andshowing the parts of the safety pin in different relative positionswhich these parts may assume in the operation of the safety pin.

In proceeding with this invention, I bend up from a piece of wire a. pinportion having a relatively stationary member and a relatively movablemember by means of coiling the wire intermediate its ends so that thesetwo portions may extend from this coil. This coil provides a springaction against which the movable member operates. The stationary memberwhich has the guard assembled therewith is provided with a tongue whichso cooperates with the guard that the movable member when in the guardand between this tongue and the guard cannot become loose without anadditional hand being utilized for moving the tongue to permit themovable member to be released. Thus this movsafety 4 claims. (o1.24;-1'56) able member may be flexed back and forth in the guard duetopressure applied to the movable member Without the danger of itsbecoming unclasped.

With'reference tothe drawings, thegwire portion of thesafety' pin'iscoiled a littlem'ore than 11/2 times at I0. to provide a relativelystationary member 'I I `and a relatively movable memberIZ extending fromthis coil.V This coil also .provides for resilient action .of the twomembersl and I2 although these members also have inherent resiliency forelastic bending themselves.

`The stationary 4member II is bent fin 'an arc asgat I3 to extend back'upon itself in the portion Id'for a shortdistance which is parallel tothe member I I and thence this portion is bent as at I5 to extendlaterally as at I6 toward the member II to provide a tongue the end I'Iof which is spaced as at I8 from this member II. The member I2 is of alength to extend beyond the tongue I6 and is pointed as at I9 at its endso that it may readily pierce a piece of fabric to which it is desiredthe pin should be attached.

A guard designated generally 2D is formed of sheet stock and is bentabout the stationary portion at its arc I3 so as to cooperate with thevarious parts of this end portion. This sheet stock provides a body 2|which extends between the portion I4 and ymember II and is folded aboutthe member I I and also about the portion I4 of this stationary member,the sheet stock being wrapped tightly about the arc I3 to hold it inplace and bent as at 22 about the portion I4 in Such a manner as toleave a space 23 between this portion and the sheet stock 2| for thereception of the member I2 (see Fig. 4). The sheet stock is also bent asat 24 to provide a lip 25 which is flared as at 26, this lip beingspaced from the body portion 2l as illustrated in the sectional views(see, for instance, Fig. 4). Thetongue I6 has its end portion I'Iresting against the lip 25, this tongue being sufciently resilient sothat it may be bent inwardly as deV sired. This lip bridges the gap I 8between the end of the tongue and the member II so as to preventmovement of the movable member I2 outwardly from the guard. This tongueis also bevelled as at 2l so as to guide the member I2 toward the body2I in its movement between the tongue and the body 2I.

'I'he member I2 is of a length suilicient to extend beyond the tongue I6and into the guard as illustrated particularly in Figs. l and 3, and inorder to insert the member I2 into clasped position within the guard itis merely necessary to position the end portion of the member I2 beneaththe flare 26 of the lip and the tongue I6 and then press in a directionas shown by arrow 29 in Fig. 8 so thai; the tongue will be back andforth between the tongue and thev body of the guard 2l will not serve topermit the escape of the member I2 from clasped position.

If it is desired to unclasp the member I2, the member will be moved fromthe position shown in Fig. 4 to the position shown in Fig. 5

as shown by the arrow 30, and then the tongue I6 will be pressedinwardly as shown in Fig. 6 and the member I2 may then be movedoutwardly as shown by the arrow 3I to the position shown in Fig. '7,where it is free to be inserted into fabric or some material as isdesired should be secured by the safety pin.

I claim:

1. A safety pin comprising relatively stationary and movable members,said stationary member being bent to extend back upon itself in spacedrelation thereto and thence laterally of the member toward thestationary member to provide a resilient tongue the end of which isspaced therefrom, a guard embracing said bent portion of the stationarymember and having a body extending on one side between said spacedstationary member and the p0rtion extending back upon it and provided onthe other side with a lip bridging the space between said tongue andmember and against which the end portion of said tongue rests, saidmovable member being of a length to extend ,beyond said tongue into saidguard and insertable between said lip and tongue by flexing of thetongue away from the lip to be locked in position between said tongueand body portion 'of the guard.

n 2. A safety pin as set forth in claim 1 wherein said tongue is beveledat its end.

"3. A safety pin as set forth in claim 1 wherein said lip is fiaredoutwardly at its free edge.

4. A safety pin as set forth in claim 1 wherein said tongue is beveledat its end on the side away from the lip. Y
